Frequently Asked Questions

What is the NTN 12580/12520 tapered roller bearing used for?

The NTN 12580/12520 tapered roller bearing assembly is used in industrial machinery and automotive applications that require support for combined radial and axial loads. Its inch-system dimensions (13/16 in bore, 1 15/16 in OD) make it suitable for gearboxes, conveyors, and wheel hubs where precise load handling and durability are needed.

What are the specifications of the NTN 4T-12580/12520 bearing?

The NTN 4T-12580/12520 is an inch-system tapered roller bearing assembly with a 13/16 in bore, 1 15/16 in OD, and 0.781 in cone width. It features a carbon steel ring and a pressed steel cage. The manufacturer part number is 4T-12580/12520, and the bearing industry number is 12580/12520.

Where to buy NTN 12580/12520 bearings worldwide?

You can source the NTN 12580/12520 tapered roller bearing worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine NTN bearings to customers across multiple industries.

How to select the correct NTN tapered roller bearing for an application?

To select the correct NTN tapered roller bearing, match the bore (13/16 in), OD (1 15/16 in), and cone width (0.781 in) to your shaft and housing dimensions. Consider load type—tapered roller bearings handle combined radial and axial loads. Verify the ring material (carbon steel) and cage material (pressed steel) suit your operating environment. Consult NTN specifications for speed and temperature limits.
